Both my boys are from the same litter . Ryd we got first then a couple weeks later Tuc got returned to the breeder and we were asked if we would like to purchase him ...... which we did . Ryder settled down a LOT , especially at night after Tuc came to live with us ! i wish we would have got the 2 at the same time . Never an issue of dominance ..... except when they are trying to rule the cat ( he is 21 lbs ! ) ! Two are just more lovin'
